Featured Work: Watershed Management Plan

The Lake Monomonac Watershed Management Plan (WMP) is currently underway.

This project represents an important step forward in protecting the long-term health of the lake we all care about. Grounded in comprehensive scientific assessment and community-based analysis, the plan is translating carefully gathered data into clear, prioritized action steps. It will identify where nutrients and sediment are entering the lake – from shoreline properties, roads, and stormwater runoff – and will outline practical, realistic solutions to reduce those impacts. The WMP will lay the groundwork for a coordinated framework for the town, state agencies, property owners, and the lake association to work together. The completed plan will be presented to the public in late 2026. To learn more about our WMP, click here.

Best Practices

Spring Clean Up with Care!

TIP: Wait to rake! Beneficial animals like salamanders use last year’s leaves to stay warm until they can make their way to our lakes and ponds. When nights stay above 50F, dispose of yard waste like leaves and grass clippings properly away from lakes, streams, or storm drains.

Why: Organic material adds excess nutrients to lakes, promoting harmful algae blooms.
